San Francisco's Light Rail To Upgrade From Floppy Disks (theregister.com) 113

Those taking public transport in the tech hub of San Francisco may be reassured to know that their rides will soon no longer be dependent on floppy disks. From a report: San Francisco Municipal Transportation Agency's director of transportation Jeffrey Tumlin told ABC that the city's automatic light-rail control system is running on outdated tech and "relies on three five-inch floppy disks" to boot up. The reporter was holding a 3.5-inch disk in the broadcast, so may have just skipped the word "point."

"It's a question of risk," Tumlin explained in a three-minute segment about the floppy replacement project. "The system is currently working just fine, but we know that with each increasing year the risk of data degradation on the floppy disks increases and that at some point there will be a catastrophic failure." The agency noted that its system was installed in 1998, when floppies were still in common use and, er, "computers didn't have hard drives."

    Retro hardware enthusiasts have this all figured out.

    They likely are not even using an actual floppy disk mechanism at all, but a floppy disk emulator with high endurance flash media which are readily available and far more reliable.  But the underlying system it is plugged into would be of more concern.  The boot media is likely just a good sound bite.

    I have used these devices a bunch on industrial CNC machines where these are common issues.  Floppy emulators, Serial port to ethernet port servers, and IDE to PCMCIA adapters to the rescue.  The core of the machine is likely going to last decades beyond the computer hardware and a new replacement in the fractions of a million each means they will keep them running with the old controllers as long as possible.

    • Would it not be easier at some point to replace the whole computer? While the "outer" hardware is made last, I don't know if the industrial PC already existed in the 5" floppy era.

        Yeah replace that 1998 computer with a newer one that supports hard drives since hard drives weren't available in 1998. What a bunch of non-sense, I bought my first hard drive in ~1985.

        • I was talking about industrial PCs. They were often older-spec, very expensive, rugged computers to be used as controllers in machines. So even if these are industrial PCs, they were already old-fashioned when they were implemented.

          I think you will find that upgrading and modernizing the systems in aircraft is quite normal. Why should it be different in a light rail or CNC machine?

          • by Sique ( 173459 )
            Because differently than airplanes, which cost millions a piece, for a CNC machine for less than 10,000 dollars, there is no business case in developing a modernization. The manufacturer will just tell you that they offer you a newer model for a really big friendship rebate.

      They could make copies of the disks too, even if they are copy protected.

      The Greaseweazle is a cheap open source device for doing this, and there are others on the market. It uses high resolution timers to read/write when the flux transitions happen on the disk, and can thus make perfect copies of any disk, regardless of format.

      Copy protection for floppies often worked by having "weak" bits, where the flux transition was in the middle of where a bit was supposed to be read. Due to slight variations in the s

        Availability is OK for now, but it's a good time to make a plan for upgrading. That new-old stock will degrade at some point even if it's never sold. Especially since it will (for a while) be seen as low value or even a white elephant.

        At some point as viable stock goes down, a few will snap up the rest of the supply and mark it up 10,000% because anyone trying to buy obviously has no options.

      • While my Roland workstation keyboard uses pc-compatible floppies, I learned that old Akai S-series samplers floppy drives weren't PC-compatible, but rather they were compatible with Amiga 600/1200. Had something to do with twisted wires. Took me long to find a replacement drive. Luckily I had a bunch in my museum, so eventually found a unit that worked.

        On top of that, Akai doesn't use DOS format floppies either, they write to disk differently. Luckily there's an easy piece of software that does that.

        The first hard disk I met for a microcomputer was a 5meg drive for the apple ][.

        It presented itself to the computer as 35 or so 143k floppies on the same controller card, so it could use the regular DOS at the time. (there might have been a patch, but I don't think so).

        And, iirc, the drive was an 8" drive.

        That was 1981; the following year, I had a 10meg drive assigned to me for development on an Osborne. It appeared as a single CP/M drive!

      Be impressed that the entire OS still fits inside 1.5MB. Even the IDE interface would be a step up from the floppy interface port, but as you say, its hardware limited based on the equipment you need to keep running. I guess the real challenge is equipment pre-USB 1.0. A usb-floppy chipset has been around forever; making one to read a flash drive would be trivial. A flash drive to physical floppy interface port would be more unique. Power was provided externally to the FDD cable. Theyve had IDE to CompactFl

    This is a great explanation of what bloat does because they have a working system on maybe a few MB of disk.
    I have a hard time believing the system would be any more reliable once replaced by a modern version taking many GB's.
    Oh yes HD's were absolutely available in 1998...
    • A tiny SSD of a few GB would be extremely reliable. Maybe run Linux for security with a DOS emulator...

    • Oh yes HD's were absolutely available in 1998...

      In 1988 I bought my first hard disk. It was 20 megabytes, and I never came close to filling it despite many, many 2d CAD drawings, (DFI iDraw. A small business' worth! I hope DFI still exists).

    Well, my CP/M 2.0 system in about 1980 had a Morrow Designs Disk Jockey (no rev yet) controller and two 19 megabyte hard disks. And I was a normal moral RF engineer at the time at Rockwell International. Computers sure as hell had hard drives well before 1998. You just had to put it in and code the BIOS yourself. Typical news media level intelligence is seen in that quote above. Um, the agency official was also "ignernt."

    • Yup - solid engineering. But engineering that needs to be replaced. This rail system provides a public service, and downtime will cost the local society a bloody mit-full. If it can't be supported, it's gotta be replaced because the cost of failure is so high. But, if there are a half-dozen spares on the shelf and they get tested from time to time, there's nothing to worry about. Boot from paper tape if that's what blows your skirt up.

            While I do not know, my guess is that they could not get a HDD with the certified reliability score they required. HDDs were _very_ flaky at that time. What they have in hardware is obviously not consumer-grade trash, as that would likely have failed a long time ago. Well, maybe. TEAC made really reliable 5 1/4 floppy drives and they had industrial versions that were even better. I have a regular one that still works, but no computer that can use it.

    The last new floppies were made around 2010 and since then ebay and that one floppy disk warehouse ran by a man in his 70s are the source of all the world's floppies. Emulators have helped reduce the amount of floppies being needed but eventually all the old stock will be unreadable and machines will be up Shugarts creek without a Gotek.

    I'd agree that a production system that actually relies on actual floppies would be rolling the dice in a deeply uncomfortable way at this point; but I'm a little puzzled by the extent of the fuss given that(admittedly, more for hobbyist and niche stuff, retrocomputers and synths from the floppy era, that sort of thing) the practice of emulating floppy drives is quite well established and, thanks to the age and (low) speed of the busses in question, pretty technically undemanding.

    If I had a floppy-dependent system I'd have wanted people evaluating commercially available floppy emulators starting 10 years ago; potentially trying to push specific developments if my system requires things that the retrocomputing guys don't(whether in terms of features or in terms of not being hand-built in small runs by hobbyists); but, barring some especially esoteric complication I'm not thinking of, slapping floppy emulators into a floppy-based system and bringing it right up to the present day in terms of media seems like it would be both a relatively simple project and much, much cheaper, lower risk, and more predictable than a full 'upgrade' that promises to rip out the old system and replace it with a full new glorious IoT something something.
    • Thank you for the best post in this thread. I hope you get your +5. The rest of the posts seems to fall into two categories. Those that think floppy emulation can be used in any situation including real-time safety-critical (it can't) and those who seem to think floppy emulation isn't a real thing at all. It's definitely a real thing and seems like the first thing that should be tried in a system that isn't safety-critical rather than an expensive upgrade for little added benefit.

    This sounds like something they should be able to manage, by substituting solid state for the mechanical drive but otherwise leaving well enough alone. Floppy drive emulators (and MFM/RLL drive emulators) are a solved problem because the retro computing crowd has needed them for years. If it has an SD card slot, then updates can even be distributed the same way as before, except the medium is postage stamp sized. Use SD card slots where the whole card clicks into place and clicks out again when pressed, and it's pretty much just a miniaturized floppy drive as far as the user is concerned.
